"Back in 2005, we charted 30 years of personal computer market share to show graphically how the industry had developed, who succeeded and when, and how some iconic names eventually faded away completely. With the rise of whole new classes of 'personal computers' - tablets and smartphones - it's worth updating all the numbers once more. And when we do so, we see something surprising: the adoption rates for our beloved mobile devices absolutely blow away the last few decades of desktop computer growth. People are adopting new technology faster than ever before." BeOS not mentioned. Would not read again. 2/10.

I believe the future of desktop/laptop computing lies in display devices. The power and miniturisation will make them be able to integrated easy. Traditional flat panels, video walls, projection systems, holographic displays together with wireless technologies will ensure the home PC survives (the size of a match box or smaller maybe).
Personally I'm bringing my household back to the days of centralised computing. I have a basement server that runs the lounge TV (DVB-T and Media files, apps etc). VNC/RDP for tablets and other devices with input devices (keyb/mouse/touch). They are all terminals to me. All running the same OS and apps.
